Summary Information‐theory procedures are powerful tools for multimodel inference and now standard methods in ecology. When performing model averaging on a given set of models, the importance predictor variable is commonly estimated by summing weights models where appears, so‐called sum (SW). However, SWs have received little methodological attention frequently misinterpreted. We assessed reliability SW selection simulated data sets including variables strongly weakly correlated to response...
Discriminant function analysis (DFA) based on morphological measurements is a quick, inexpensive, and efficient method for sex determination in field studies cryptically monomorphic bird species. However, behind the apparent standardization relative simplicity of DFA lie subtle differences pitfalls that have been neglected some studies. Most these concerns directly affect assessment discriminant performance, parameter crucial importance practice because it provides measure quality an...
Abstract In a previous article, we advocated against using the sum of Akaike weights (SW) as metric to distinguish between genuine and spurious variables in Information Theoretic (IT) statistical analyses. A recent article (Giam & Olden, Methods Ecology Evolution , 2016, 7, 388) criticises our finding instead argues favour SW. It points out that (1) performed biased data‐generation procedure (2) erroneously evaluated SW on its capacity estimate proportion variance data explained by...
In recent years, considerable research interest in behavioral ecology has focused on characterizing and understanding individual differences behavior that are consistent over time across contexts, termed animal "personalities," correlations between various behaviors syndromes. Although there is some evidence personality among individuals within populations can be genetically based adaptive, when how emerge a population not well understood, but of general interest. Here, using juveniles the...
Many animals nest or roost colonially. At the start of a potential foraging period, they may set out independently await information from returning foragers. When should such individuals act and when wait for information? In social insect colony, example, transfer greatly increase recruit's probability finding food, it is commonly assumed that this will always colony's net energy gain. We test assumption with mathematical model. Energy gain by colony function both food sources duration their...
In fall, Myzus persicae (Sulzer) (Homoptera: Aphididae) may exhibit population resurgence in winter oilseed rape France. This arise from pyrethroid treatments against Coleoptera (Psylliodes chrysocephala L.) that either kill parasitoids present during treatment or prevent recolonization by off-crop parasitoids. We studied the impact of Diaeretiella rapae (M’Intosh) (Hymenoptera: Braconidae) on populations M. when were introduced deltamethrin-treated plants at increasing intervals after...
In the monogamous convict cichlid, mismatched partners become better parents by adjusting their behaviors to each other.
Compromises between speed and accuracy are seemingly inevitable in decision-making when depends on time-consuming information gathering. In collective decision-making, such compromises especially likely because is shared to determine corporate policy. This political process will also take time. Speed–accuracy trade-offs occur among house-hunting rock ants, Temnothorax albipennis . A key aspect of their quorum sensing a potential new nest. Finding sufficient number nest-mates, i.e. threshold...
Many trophically transmitted parasites manipulate their intermediate host phenotype, resulting in higher transmission to the final host. However, it is not known if manipulation a fixed adaptation of parasite or dynamic process upon which selection still acts. In particular, local has never been tested manipulating parasites. this study, using experimental infections between six populations acanthocephalan Pomphorhynchus laevis and its amphipod Gammarus pulex, we investigated whether...
Animals foraging in the wild have to balance speed of decision making and accuracy assessment a food item's quality. If resource quality is important for maximizing fitness, then duration may be conflict with other crucial time consuming tasks, such as anti-predator behaviours or competition monitoring. Individuals facing risk predation and/or should adjust and, consequence, their level choosiness resources. When exposed predation, forager could either maintain its items but accept reduction...
Abstract Studies concerning long‐term survival of honeybees raise the problem statistical analysis mortality data. In present study, we used a modeling approach data caged bees under chronic exposure to two pesticides (imidacloprid and deltamethrin). Our model, based on Cox proportional hazard is not restricted specific functional form, such as in parametric approaches, but takes into account multiple covariates. We consider only pesticide treatment also nuisance variable (variability...
The pace-of-life syndrome (POLS) hypothesis is an extended concept of the life-history theory that includes behavioural traits. studies challenging POLS often focus on relationships between a single personality trait and physiological and/or trait. While pathogens represent major selective pressure, few have been interested in testing syndrome, several fitness components including immunity. aim this study was to address question mealworm beetle, Tenebrio molitor, model species immunity...
We consider an agent that must choose repeatedly among several actions. Each action has a certain probability of giving the energy reward, and costs may be associated with switching between The does not know which highest reward probability, probabilities change randomly over time. study two learning rules have been widely used to model decision-making processes in animals—one deterministic other stochastic. In particular, we examine influence rules' ‘learning rate’ on agent's gain. compare...
One of the most important decisions that an animal has to make in its life is choosing a mate. Although studies sexual selection assume mate choice rational, this assumption not been tested seriously. A crucial component rationality animals exhibit transitive choices: if individual prefers option over B, and B C, then it also C.We assessed transitivity choice: 40 female convict cichlids had series binary choices between males varying size. Ninety percent females showed choices. The mean...
In humans, affective states are a key component in pair-bonding, particularly the early stage of relationship. Pairing with high-quality partner elicits positive which, turn, validate and reinforce mate choice. Affective thus strongly affect pair stability future reproductive success. We propose generalizing link between pair-bonding to encompass other monogamous species exhibiting biparental care, chiefly where success critically depends on coordination partners. The convict cichlid...
Most birds incubate their eggs to allow embryo development. This behaviour limits the ability of adults perform other activities. Hence, incubating trade off incubation and nest protection with foraging meet own needs. Parents can either cooperate sustain this tradeoff or alone. The main cause reproductive failure at stage is predation reduce risk by keeping location secret. Arctic sandpipers are interesting biological models investigate parental care evolution as they may use several...
Although personality (consistent inter-individual differences in behavioural traits across time and/or contexts) and syndromes (suites of correlated traits) have been widely studied the last decades, origin development these during ontogeny are still underexplored. In this context, species undergoing metamorphosis special interest. To date, however, persistence has only little investigated organisms complete such as holometabolous insects, although kind studies may provide important insights...
